Yes, when examining the "http://maps.zh.ch/wfs/FnsNSWFS?TYPENAME=svo_zonen&SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType"; you can see : <element name="msGeometry" type="gml:GeometryPropertyType" minOccurs="0" maxOccurs="1"/> So the geometry type is undefined. OGR then reports a unknown geometry type. There could be a mix of geometries in such a layer. I guess that QGIS will inspect the whole layer content after having downloaded it to determine the geometry type, but the OGR WFS driver doesn't do that for effeciency purposes. It can operate on arbitrarily huge layers in streaming mode (true for OGR 1.10) _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
